13 UICC interface during PSM

31.1273GPPnon-removable Universal Subscriber Identity Module (nrUSIM) application behavioural test specificationRelease 17TSUICC-terminal interaction

13.1 UICC interface in PSM handling for E-UTRAN – No UICC deactivation in PSM

13.1.1 Definition and applicability

PSM is intended for UEs that are expecting only infrequent mobile originating and terminating services and that can accept a corresponding latency in the mobile terminating communication. In order to reduce power consumption while in PSM, and only in case the PIN of the USIM is disabled, the ME may optionally deactivate the UICC after entering the PSM.

13.1.2 Conformance requirement

CR 1 In order to reduce power consumption while the ME is in PSM, and only in case the PIN of the USIM is disabled, the ME may optionally deactivate the UICC (as specified in clause 6A.1 of TS 31.101 [33]) after entering the PSM.

Reference:

– TS 31.102 [19], clause 5.1.10;

– TS 24.301 [21], clauses 5.3.5 and 5.3.11.

– TS 31.101 [33], clause 6A.1.

13.1.3 Test purpose

1) To verify that UE does not deactivate the UICC in case the PIN for the USIM is enabled and verified.

13.1.4 Method of test

13.1.4.1 Initial conditions

The UE is configured to use Power Saving Mode.

The UE is configured to use the timer T3324 set to T3324_V.

The E-USS transmits on the BCCH, with the following network parameters:

– TAI (MCC/MNC/TAC): 246/081/0001.

– Access control: unrestricted.

– Access control: unrestricted.

The default E-UTRAN UICC is used with the following exceptions:

EFUMPC (UICC Maximum Power Consumption)

Logically:

UICC maximum power consumption: 60 mA

Operator defined time out (T_OP): 5 seconds

Additional information: UICC does not require increased idle current

UICC does not support the UICC suspension procedure

13.4 UICC interface in PSM for E-UTRAN – SUSPEND UICC

13.4.1 Definition and applicability

PSM is intended for UEs that are expecting only infrequent mobile originating and terminating services and that can accept a corresponding latency in the mobile terminating communication. If the UICC supports the UICC suspension mechanism (SUSPEND UICC command), the ME may suspend the UICC after entering the PSM. In this case, the ME shall successfully resume the UICC before it can leave the PSM.

13.4.2 Conformance requirement

CR 1 If the UICC supports the UICC suspension mechanism (SUSPEND UICC command), the ME may suspend the UICC after entering the PSM. In this case, the ME shall successfully resume the UICC before it can leave the PSM.

Reference:

– TS 31.102 [19], clause 5.1.10;

– TS 24.301 [21], clauses 5.3.5, 5.3.11 and 5.5.1.2.2.

– TS 31.101 [33], clause 11.1.22.

13.4.3 Test purpose

1) To verify that after reading EFUMPC and entering the PSM the ME sends a SUSPEND UICC command to the UICC in case the UICC indicates the support of the SUSPEND UICC command.

2) To verify that the ME resumes the UICC before it can leave the PSM.
